Strange vision: a retinal ganglion cell that violates many rules
报告人：Dr. KwoonWong, Assistant Professor, University of Michigan
Dr. Wong earned his Ph.D. Degree in Biology from Harvard University in 2003 and completed his postdoctoral training at David Berson's laboratory at Brown University in 2009. Dr. Wong is currently an assistant professor at University of Michigan at Ann Harbor.Dr. Wong is one of the pioneers in the discovery of intrinsically photosensitive retinal ganglion cells (ipRGCs). He has made tremendous contribution to the understanding of structural and functional properties of ipRGCs and published more than 30 articles in top journals including Nature, PNAS, Neuron, and Journal of Neuroscience. He served as a peer reviewer for more than 20 top journals.
Vision begins in the retina, where photoreceptor cells convert light into electrical signals that the visual system can interpret. For over a century, rods and cones were thought to be the only photoreceptors. But a flurry of recent studies discovered a third class of retinal photoreceptors: a subset of ganglion cells that senses light using an invertebrate-like photopigment, melanopsin, which activates a phototransduction cascade drastically different from the rod/cone cascade. These ganglion-cell photoreceptors generate very unusual light responses that drive subconscious, non-image-forming visual behaviors. In this talk, Dr. Wong will present many additional surprising properties of these exotic neurons.
